(a,b,c,d) d.p. (2,3,5,8)=
 \frac{a}{2} =  \frac{b}{3} =  \frac{c}{5} =  \frac{d}{8}

 \frac{a}{2} = 2k

 \frac{b}{3} = 3k

 \frac{c}{5} = 5k

 \frac{d}{8} = 8k

Si o sa facem operatia : 2k+3k+5k+8k = 360·
k=360:18
=K =20
apoi imultim
 \frac{a}{2} = 2 x 20 = 40 ( a )

 \frac{b}{3} = 3 x 20 = 60 ( b )

 \frac{c}{5} = 5 x 20 = 100 (c)

 \frac{d}{8} = 8 x 20 = 160 (d )
